如何更改drupal 8 REST API核心消息

我正在使用以下补丁请求更新密码：

{
  "_links": {
    "type": {
      "href": "{url}/rest/type/user/user"
    }
  },
  "pass": [
    {
    "existing":"admin",
    "value":"123456789"
    }]
}

如果现有密码错误，drupal将返回如下消息

Unprocessable Entity: validation failed.pass: Your current password is missing or incorrect; it's required to change the Password.

我想删除这个“不可处理的实体：”内容，并希望向用户显示清晰的消息

Your current password is missing or incorrect; it's required to change the Password.

非常感谢您的帮助
